Abstract
Blood-brain barrier (BBB)-permeable components in the methanolic extract of Nelumbo nucifera flowers showed accelerative effects on neurite outgrowth in PC-12 cells. Among the constituents isolated from N. nucifera flowers in our previous study, aporphine-type alkaloids, lirinidine, asimilobine, N-methylasimilobine, and pronuciferine, showed accelerative effects. Lirinidine, N-methylasimilobine, and an alkaloid-rich diethyl ether fraction at low concentrations increased the expression of mRNAs coding for TrkA, Vav3, and Rac1. In addition, good permeability of asimilobine and N-methylasimilobine was confirmed using an in vitro BBB model. Asimilobine and N-methylasimilobine are considered to be suitable as seed compounds of drugs for Alzheimer's disease, because of their activity and BBB permeability.Entities:
